Who knew filling a hay bag could be so neat and easy after all? Roll the hay bag helper up insert it into the hay bag and let it expand. Holds any cloth hay bag or small holed hay net open and makes it free standing. Toss your hay in take the insert out and away you go. This can also be used in trash bags to fill shavings, grain, laundry, recyclables or trash. If the StableHand ever loses its ability to fully spring open, reverse roll once or twice.
